COMPLETE HARVESTER*- SPECIFICATION forming part of Letters PatentNo. 768,881, datedAugust 30, 1904. Application led April 30, k1902. Serial No. 105,367. (No model.)

-To all whom it may concern:

Be it known that we, JAMES MORROw and ROBERT BLAKE INIORROW, agricultural implement and machine manufacturers, both subjects of the King of Great Britain and Ireland, residing at Nos. 33 to 49 Bouverie street, Carlton, in the British State of Victoria, Commonwealth of Australia, have invented a certain new and useful Improvement in Complete Har- IO vesters, ot' which the following is a Specification.

This invention relates to harvesting-machines which strip, clean, and bag grain while at work in the field; and the improvements I5 consist mainly of the combination and arrangement of the various parts comprised in the harvester.

The invention will now be described, aided by a reference to the attached sheets of draw- 2o ings, throughout which similar letters will be used 'to denote corresponding parts.

Figure l is a general plan ot' a complete harvester having our improvements embodied in it; Fig. 2, an elevation of its near side; Fig. 3, an elevation of its Off sidegFig. 4, a back elevation of the machine and showing it furnished with a grain-box; Fig. 5, a vertical longitudinal section taken on line a a, Fig. l, and showing in dotted lines a chaff-box attached to back of machine; Fig. 6, an off-side elevation of the winnower or riddle-box and fan as supported on its frame. Fig. 7 is a side View of the appliances for catching and bagl ging the chaff; and Figs.8 and 8 are detailback 3 5 and side views, respectively, of the mechanism for finally dressingI the grain prior to its reaching the grain-box. Fig. 9 is a plan View of the lipped riddle, and Figs. 10 and ll are detail views Showing the operating connections to the chaff-box K.

f Ais the body foundation-frame, hereinafter called the body-frame, supported on an axle B, borne by wheels B', the near-side one of which acts as the main drive-wheel. The body-frame A may either be of wood or metal,

having on its under side a transverse T or angle-iron stay A2 and a post a', below which is a diagonal bar A', which carries a toothed segment X3.

' from the riddles is blown into and retained Eis the comb at front of body; E', concave, 50 and E2 the beaters; F, the throat or chute leading from beaters to a peg or damp-weather threshing-drum G and delivering theretoy at` a position below its center, the said peg-drum working in combination with a double-finger concave G, the threshed heads from which fall to a chute G2, leading to the riddles or screens O2. The clean or screened grain leaves the riddles by a grain-spout H, which leads to the well ofan elevator I, which conveys by cups 2 the grain to'a spout c', delivering to a bagging-bin J, while the unthreshed heads are deposited -in a headings-spout L at back of riddles 'and returned by an elevator L to the peg-drum G to be rethreshed. The chaff by a chai-bin K, which is adjustably supported at tail end of machine, and it is provided with a hinge-bottom K', which can be opened at intervals to discharge its contents by a rod K2, connected with the bottom, passing to an operating-lever nearthe drivers seat. K3 is a rod also controlled by an operating-lever and designed to adjust the horizontal position ot' the chaff-box.`

The fan Q -and riddle-box R are carried by a frame C, preferably secured on main axle B by keys R2, said main axle being in turn made secure to the main bars of the fore-carriage D. The riddle-box is supported in position by angularly-arranged spring-stays R3, straps R4, and vertical rods R5, all carried at their lower ends by frame C in such a manner as to permit the riddle-box to receive its side shake, while the fan Q has both its end openings furnished with adjustable windboards S, hinged at s. The position of the boards S over the openings is adjusted by a lever S, terminating near the drivers seat, said lever being held at the desired position by the notches S2 in it engaging a suitable catch; also, in the fan-delivery mouth are two,

Abutterfly boards or valves T and T', which can be secured by end thumb screws at the desired angle to adjust the direction of the blast onto the screens.

The screens or riddles C2 are of punched or perforated metal, the upper ones being ofthe lip type, while they are held in position at their back ends by plates c, having diagonal slots formed in them, and which plates are secured upon the side cheeks by thumb-screws. To enable any wild oats to be caught and be separated Afrom the other grain at the earliest moment after once passingover end of sieves, a long narrow opening or port C is provided at the point of junction between the sliding' tail-board C4 of riddles and the headings-chute L, and said port C3 is furnished with a sliding or adjustable cover C5, by means of which its width is regulated. The said narrow opening or port C3 leads by a chute C under the headings-chute L to a box or receptacle C2, in which the wild oats are retained. Said adjustable cover C is made or' a strip of sheet metal having, say, three transverse oblong holes in it through which screws C8 pass and by which it is secured at the desired position.

At the back of the peg-drum and over the riddles is a self-adjusting grain shield or arrester N, which when the machine is working in a low crop automatically comes into position and prevents the grain and heads as they are delivered to the riddles being thrown too far forward thereon, as the shield arrests the grain and causes it to fall at the desired position. It consists of a plate or shield hinged at n to a cross-bar O, which is supported above the riddles by side framing P, carried on body-frame A. rlhe free edge of the shield is backlnost, while under each side of its top is a roller N', supported at upper end of a bar N2, the lower end of which is secured to the cheek or side of the seconds-box. Said shield is preferably made of sheet metal and of a width to suit circumstances and bent t0 a curved section to cast or direct the grain striking it downward upon the uppermost screen.

rlhe gear for imparting motion to the fan Q is derived from the main spindle U, which receives its motion through pinion Ul from the internal spur-wheel V on the main wheel B. U2 is a lever for placing' pinion U in or out oi' gear. The said main spindle U has a sprocket-wheel VD on it, which communicates motion by chain-belt V2 to one of a double i sprocket V' running loose on axle B, the other of said double sprockets V imparting motion by belt N2 to a sprocket V4 on the fan-spindle Q.

To impart a side shake to the riddles, the other end oi' the fan-spindle Q2 communicates motion by bevel-gear XV to a shaft VV, upon which is an adjustable throw crank-disk W2, which works a connecting-rod or pitman W2, passing to a pin WV* on opposite side of the riddle-box. [f so desired, an adjustable throw eccentric or a ball-bearing pin, mounted on an adjusting-screw and carried either in a disk or a crank-arm, may be provided.

To enable the driver to closely-watch the grain upon riddles, a mirror A2 is supported on a standard A3, carried on the back part of frame C, the mirror being at such a position that the riddles are reflected into it and can be 4seen by the driver from his seat.

The fore-carriage D is borne at its front above a steering-wheel D', while its hind part is supported by the main axle B at each side oi' the main drive or traction wheel B', the hub oi' which is provided with a drum to receive a brake-strap B2, which is connected by a rod with a foot-lever B2, .arranged adjacent to the drivers seat. The said steering-wheel D has a holed draft-bar CZ attached to its moving or swivel frame, while a holed draftbracketd/ is secured to the fore-carriage, and said bars d and d can be coupled together by a link (Z2, attached to a draw-hook (Z3, and when s0 coupled and drawn by the horses the wheel D immediately follows the direction of travel of the horses. A shackle d* is provided on the wheel-frame to receive the usual three-horse draft-gear. D2 is a couplingpiece on head of steering-wheel post, and D3 and D4 are respectively hand and foot steering-levers, which are capable of being secured to'said piece D2.

To raise and lower the body, a worm w on vertical spindle X is geared with the segment X2, said spindle being rotated by the handwheel M and having combined with it a bevelclutch fr, which allows the worm to be rotated to lift the comb without the driver having to press his foot on the' releasing-lever X2; but said clutch has to be lifted to allow the wormg'ear to rotate to lower thecomb. Said clutch is iitted on a square part or' the spindle X, and its jaws engage jaws formed at top of the worm-bracket Z.

To obtain a more equable strain upon the raising and lowering gear, a longitudinal flat spring g (shown by dotted lines, Figs. l and 5) is secured at about its center to the stationary sleeve on the main axleB or to any stationary part on the fore-carriage, the one end of said spring extending to near the back of machine and bearing tightly upon under side of back part of body-frame, while the other end of the spring g bears in a similar manner upon under side of the front part of the bodyframe or under the diagonal bar A, or the ends of the springs may bear upon any bar projecting from the body. The said spring thus also serves as a balance, tending to brllng the machine to its normal horizontal position. A spiral or coiled spring may be arranged between the fixed and movable parts of machine to eiect the same purpose as springg.

rlhe comb E has a transverse roller E3 arranged above it, supported by b earings in ad.- justable slotted links carried by arms E2, the roller being aranged above the comb to regulate the feed in high crops and to avoid its taking in too much straw, and so losing grain by the head s4 beating against the drum-casing E.

The elevators are driven by chain-belt leading from sprocket l2 on main drive-spindlejU IOO IIO

to a sprocket I on upper spindle ot' elevators and which spindle imparts motion to both elevators, while the peg-drum G is driven by a belt z/,which derives motion from a pulley on the 'beater-spindle Y, the latter having a pinion Y on it to which motion is imparted by spur-gear Y2 and Y3 `from the main drivespindle U.

Under the clean-grain bin J a bagging-platform is Asometimes arranged to support the bags while illing, the grain passing to the bags through suitable cut-off spouts J and the platform being so suspended that a jerking motion can be imparted to it by working a hand-lever. y

The chai blown over the rear end of the riddles R is, as shown in Fig. v7, led by an apron provided to the well L2 of an elevator L3, assembled at back of machine, and. said elevator delivers the chaff to a bag Iarranged under its mouth, a small bag-platform L5 being provided between the body-frame barsA at back of machine to seat the bag upon. The elevator may be driven by a belt from a pulley on any convenient spindle of the machine.

To eect a'second or linal dressing. of the grain,we arrange, as shown in Figs. 8 and 8, a small fan I3 on the machine*say on the near end of the damp-weather spindle G-and convey the air-current through a branch pipe I4 to the chute a' leading to the grain-bin J, so that as the grain is passing therethrough it will be acted on by air-current, or, if preferred, the grain may pass over a sieve-bottom formed in said chute c' and the air-current pass upward through it in order to carry off any light stuff.

In many machines no provision is made for readily altering the speed of the damp-weather beater to suit the varying weather in which the machine has to work without having to unship a pulley or sheave and alter the drivingbelt. We have overcome the difficulty by combining with and arranging' on the end part of both the main-beater-drum spindle Y' and the damp-weather-drum spindle G a stepped or cone pulley G3, arranged reversewise on said spindle in order that the speed may bealtered by simply placing-the belt which communicates motion between them on the requisite steps of the pulleys.

aving now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

In a combined harvester and thresher, a su pporting-axle, a main frame movably supported thereby, harvesting and threshing devfices carried by-said main frame, a second framerigidly supported by said axle, a fan and riddle-box carried by said rigid frame, and an adjustable discharge-port C3 in said riddle-box,
